DETAILED DESCRIPTION

[0017] In order to make the purpose and advantages of the present application more clear and explicit, the present application is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the present application, and does not strictly limit the specific protection scope requested by the present application.

[0018] Example one AsFigures 1 to 2 As shown, it is the first embodiment of the present application, which provides a positioning device for neck, chest, limbs and chest joint trauma, comprising a first pad 10, one side of the first pad 10 is provided with a second pad 11, the top of the first pad 10 and the top of the second pad 11 are installed with a shoulder strap assembly 12; A telescopic structure 20 is arranged between the first pad 10 and the second pad 11, the telescopic structure 20 comprises a plurality of first chest belts 21 fixedly connected at both ends of the first pad 10 respectively, a plurality of second chest belts 22 are slidably installed at both ends of the second pad 11, the first chest belts 21 and the second chest belts 22 are equal in number and one-to-one correspondence, and the first chest belts 21 and the second chest belts 22 are detachably installed with elastic belts 23.

[0019] It should be noted that the first pad 10 and the second pad 11 are respectively matched with the front and back sides of the chest cavity of the patient, the inner side of the shoulder strap assembly 12 is matched with the shoulder of the patient, which is used to hinder the device from sliding down along the patient's body, the first chest belt 21 and the second chest belt 22 are both foldable cloth belts, the elastic belt 23 is made of elastic material, the elastic belt 23 is provided with a plurality of elastic belts 23, the number of the elastic belt 23 and the first chest belt 21 is equal and one-to-one correspondence with the first chest belt 21, the number of the elastic belt 23 and the second chest belt 22 is equal and one-to-one correspondence with the second chest belt 22, there is only one elastic belt 23 between each first chest belt 21 and the corresponding second chest belt 22, the plurality of elastic belts 23 are arranged in vertical direction, in the initial state, the distance between the first chest belt 21 and the second chest belt 22 corresponding to the elastic belt 23 at different height positions is different, and the chest cavity is in a normal limiting state.

[0020] In use, the second chest band 22 at different height positions is slid along the second gasket 11, the distance between the second chest band 22 at different height positions and the first chest band 21 is adjusted respectively, so that the tightness of the elastic band 23 at different height positions is different, thereby by sliding the second chest band 22, when the patient's chest cavity is in a reduced state, only one elastic band 23 at both ends of the first gasket 10 is in a stretched state, and the remaining elastic bands 23 at different height positions are in different degrees of relaxation, at this time, the elastic band 23 pulls the first gasket 10 and the second gasket 11 through the first chest band 21 and the second chest band 22 to normally limit the chest cavity, when the patient inhales, the chest cavity expands, so that the distance between the second gasket 11 and the first gasket 10 increases, in the process that the second gasket 11 and the first gasket 10 move away from each other, first, only one elastic band 23 at both ends of the first gasket 10 is in a stretched state, and the relaxation degree of the remaining elastic bands 23 at different height positions increases in turn, the elastic band 23 pulls the first gasket 10 and the second gasket 11 through the first chest band 21 and the elastic band 23 to limit the chest cavity under the action of elasticity, after the distance between the second gasket 11 and the first gasket 10 increases, the distance between the first chest band 21 and the second chest band 22 increases, driving one elastic band 23 that is relatively relaxed to elongate, so that the elastic band 23 and the previous elastic band 23 pull the first gasket 10 and the second gasket 11 to limit the chest cavity under the action of elasticity, after the distance between the second gasket 11 and the first gasket 10 continues to increase, the distance between the first chest band 21 and the second chest band 22 continues to increase, driving one elastic band 23 that is more relaxed to elongate, so that the elastic band 23 and the previous elastic band 23 pull the first gasket 10 and the second gasket 11 to limit the chest cavity, and so on, the process that the second gasket 11 and the first gasket 10 move away from each other makes the chest cavity gradually increase in limitation, compared with the prior art, the initial limitation of the chest cavity by the band is reduced, and the chest cavity is difficult to expand, when the patient exhales, the chest cavity shrinks, so that the distance between the second gasket 11 and the first gasket 10 decreases, in the process that the second gasket 11 and the first gasket 10 move close to each other, first, the elastic band 23 at both ends of the first gasket 10 is in a stretched state, and the stretching degree of the elastic band 23 at different height positions decreases in turn, due to the decrease of the distance between the second gasket 11 and the first gasket 10, the distance between the first chest band 21 and the second chest band 22 decreases, so that the elastic band 23 with the smallest stretching degree changes to a relaxed state, the elastic band 23 no longer pulls the first gasket 10 and the second gasket 11 to limit the chest cavity through the first chest band 21 and the second chest band 22, after the distance between the second gasket 11 and the first gasket 10 continues to decrease, the distance between the first chest band 21 and the second chest band 22 continues to decrease, so that the elastic band 23 with smaller stretching degree changes to a relaxed state, and so on, in the process that the second gasket 11 and the first gasket 10 move close to each other, the chest cavity gradually decreases in limitation and still exists,Until only one elastic band 23 is stretched at each end of the first pad 10, the chest cavity is in a normal confinement state. Compared with existing technologies, this reduces the possibility of the initial confinement of the chest cavity by the strap being too small, leading to difficulty in confinement after the chest cavity shrinks. The maximum confinement of the chest cavity is gradually adjusted by sequentially stretching the elastic bands 23 at different heights, reducing patient discomfort. Conversely, the minimum confinement of the chest cavity is gradually adjusted by sequentially relaxing the elastic bands 23 at different heights, improving the reliability of positioning and thus enhancing the convenience of trauma localization.

[0021] Because the elastic band 23 is detachably installed between the first chest band 21 and the second chest band 22, and the slack of the elastic band 23 can be adjusted by sliding the second chest band 22, when it is necessary to adjust the gradual change in the limitation of the chest cavity during the patient's inhalation, some elastic bands 23 at different height positions can be removed. For example, every other elastic band 23 can be removed, and the slack of the elastic bands 23 at different positions can be gradually increased by sliding the second chest band 22. This increases the gradual change in the limitation of the chest cavity during the expansion of the chest cavity during the patient's inhalation. When adjusting the gradual change in the chest cavity's confinement during the patient's exhalation, the removed elastic band 23 is reinstalled between the first chest band 21 and the second chest band 22. By sliding the second chest band 22, the relaxation degree of the elastic band 23 at different positions increases sequentially. This reduces the gradual decrease in chest cavity confinement during the patient's exhalation, making the gradual decrease in chest cavity confinement smoother and reducing patient discomfort. By removing and installing the elastic band 23 at different heights, the gradual change in chest cavity confinement can be adjusted, improving the convenience of trauma localization.

[0022] Example 2 Reference Figures 1 to 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0023] like Figure 2 and Figure 5 As shown, the second chest strap 22 is slidably connected to the second pad 11. Both ends of the second pad 11 are fixedly connected with several limiting rings 31. The number of limiting rings 31 is equal to that of the second chest strap 22 and they correspond one-to-one. One end of the second chest strap 22 is detachably connected to the elastic band 23. The other end of the second chest strap 22 is slidably connected to the limiting ring 31. The end of the second chest strap 22 away from the elastic band 23 passes through the limiting ring 31 and then bends around the outside of the limiting ring 31 toward the end closer to the elastic band 23 and is detachably connected to the second chest strap 22 itself.

[0024] According to the above structure, when it is necessary to adjust the distance between the first chest band 21 and the second chest band 22, the end of the second chest band 22 away from the elastic band 23 is separated from the second chest band 22 itself, the second chest band 22 is slid along the second gasket 11, so that the distance between the second chest band 22 and the first chest band 21 is increased or decreased, the end of the second chest band 22 away from the elastic band 23 is bent around the outside of the limiting ring 31 to the end close to the elastic band 23, and then connected with the second chest band 22 itself, so that the limiting ring 31 limits the bent second chest band 22, and hinders the second chest band 22 from moving to the end close to the elastic band 23, thereby adjusting the distance between the first chest band 21 and the second chest band 22, and facilitating the adjustment of the relaxation degree of the elastic band 23.

[0025] As shown in Figure 2 and Figure 5 , the first adhesive part 32 is fixedly connected to the side of the second chest band 22 away from the second gasket 11, and the second adhesive part 33 is fixedly connected to the end of the second chest band 22, and the first adhesive part 32 and the second adhesive part 33 are adhesively connected together, and the first adhesive part 32 and the second adhesive part 33 are located on the same side of the second chest band 22.

[0026] It should be noted that the end of the second chest band 22 and the second chest band 22 itself are detachably connected together through the first adhesive part 32 and the second adhesive part 33, the first adhesive part 32 and the second adhesive part 33 together constitute a magic tape, the magic tape is a prior art, and is used to realize quick adhesion and damage-free separation of the first adhesive part 32 and the second adhesive part 33, the first adhesive part 32 is a loop surface of the magic tape, the second adhesive part 33 is a hook surface of the magic tape, and is used to reduce exposure of the hook surface after adhesion of the first adhesive part 32 and the second adhesive part 33, so as to avoid discomfort of the patient, the length dimension of the first adhesive part 32 is greater than that of the second adhesive part 33, and is used to adjust the adhesion position of the first adhesive part 32 and the second adhesive part 33 to adjust the length of the second chest band 22 after being bent and overlapped with itself.

[0027] According to the above structure, when it is necessary to adjust the distance between the first chest band 21 and the second chest band 22, the first adhesive part 32 and the second adhesive part 33 are separated and then adhesively connected together again, and the overlapping position of the first adhesive part 32 and the second adhesive part 33 after being adhesively connected again is adjusted, so as to adjust the length dimension of the second chest band 22 after being bent and overlapped with itself, thereby facilitating the adjustment of the distance between the second chest band 22 and the first chest band 21.

[0028] As shown in Figure 2 and Figure 5 , a plurality of sliding sleeves 41 are detachably connected to the two ends of the second gasket 11, the sliding sleeves 41 are in sliding cooperation with the second chest band 22, and the number of the sliding sleeves 41 is equal to and corresponds to that of the second chest band 22.

[0029] It should be noted that the second chest band 22 and the second gasket 11 are connected together through the sliding sleeve 41.

[0030] According to the above structure, the sliding sleeve 41 cooperates with the second chest band 22 to make the sliding process of the second chest band 22 along the second gasket 11 more stable, and the sliding sleeve 41 is detachably connected with the second gasket 11, which facilitates disassembly and replacement of the sliding sleeve 41 and improves the flexibility of the device.

[0031] As shown in Figure 2 and Figure 5 , the sliding sleeve 41 is fixedly connected with a third adhesive part 42 on the side close to the second gasket 11, and the second gasket 11 is fixedly connected with a fourth adhesive part 43, and the third adhesive part 42 and the fourth adhesive part 43 are adhesively connected together.

[0032] It should be noted that the third adhesive part 42 and the fourth adhesive part 43 are detachably connected together between the sliding sleeve 41 and the second gasket 11, and the third adhesive part 42 and the fourth adhesive part 43 together form a magic tape, which is a prior art for quickly adhering and non-destructively separating the third adhesive part 42 and the fourth adhesive part 43. The fourth adhesive part 43 is the hair surface of the magic tape, and the third adhesive part 42 is the hook surface of the magic tape, which is used to reduce the exposure of the hook surface after the third adhesive part 42 and the fourth adhesive part 43 are adhered, so as to reduce the discomfort of the patient. The length of the fourth adhesive part 43 is greater than the length of the third adhesive part 42, which is used to adjust the adhesive position of the third adhesive part 42 and the fourth adhesive part 43 to adjust the position of the sliding sleeve 41 on the second gasket 11.

[0033] According to the above structure, when it is necessary to adjust the position of the sliding sleeve 41 on the second gasket 11, the third adhesive part 42 and the fourth adhesive part 43 are separated and then adhered together again, and the position of the sliding sleeve 41 on the second gasket 11 is adjusted by adjusting the overlapping position of the third adhesive part 42 and the fourth adhesive part 43 when they are adhered again, which facilitates the adjustment of the distance between the second chest band 22 and the first chest band 21 of different heights and improves the flexibility of the device.

[0034] As shown in Figure 3 and Figure 6 , the elastic band 23 is fixedly connected with a plug 51 on one end close to the second chest band 22, and the second chest band 22 is fixedly connected with a slot 52 on one end close to the elastic band 23, the plug 51 and the slot 52 are slidably connected in the vertical direction, the slot 52 is provided with a limiting slot 53, the limiting slot 53 is in communication with the inner side of the slot 52, and the plug 51 and the limiting slot 53 are slidably connected in the horizontal direction.

[0035] It should be noted that the plug 51 and the slot 52 are also rotatably connected, and the second chest band 22 and the elastic band 23 are detachably connected together through the plug 51 and the slot 52.

[0036] According to the above structure, when it is needed to install the elastic band 23 and the second chest band 22 together, the plug block 51 is inserted into the plug slot 52, the second chest band 22 and the elastic band 23 are limited in the horizontal direction, the plug block 51 is rotated, the plug block 51 is inserted into the limiting slot 53, the second chest band 22 and the elastic band 23 are limited in the vertical direction, so that the elastic band 23 and the second chest band 22 are installed together, when it is needed to separate the elastic band 23 and the second chest band 22, the plug block 51 is rotated, the plug block 51 is separated from the limiting slot 53, the limitation of the second chest band 22 and the elastic band 23 in the vertical direction is released, the plug block 51 is pulled out of the plug slot 52, the plug block 51 is separated from the plug slot 52, and the limitation of the second chest band 22 and the elastic band 23 in the horizontal direction is released.

[0037] As shown in Figure 3 and Figure 6 , the plug block 51 includes a limiting plate 54 fixedly connected to one end of the elastic band 23 close to the second chest band 22, the limiting plate 54 is slidably connected with the limiting slot 53 in the horizontal direction, one end of the limiting plate 54 away from the elastic band 23 is fixedly connected with a rotating column 55, the rotating column 55 is slidably connected with the plug slot 52 in the vertical direction, and the rotating column 55 is also rotatably connected with the plug slot 52.

[0038] It should be noted that the side surface of the plug slot 52 is provided with a sliding groove in the vertical direction, the sliding groove is slidably connected with the limiting plate 54 in the vertical direction, and the sliding groove is used for the limiting plate 54 to slide along the sliding groove to make the process of inserting the plug block 51 into the plug slot 52 more stable.

[0039] According to the above structure, after the rotating column 55 is inserted into the plug slot 52 and rotates along the plug slot 52, the rotating column 55 drives the limiting plate 54 to rotate along the plug slot 52, so that the limiting plate 54 is inserted into the limiting slot 53, the plug slot 52 hinders the rotating column 55 from moving in the horizontal direction, and the limiting slot 53 hinders the limiting plate 54 from moving in the vertical direction, thereby facilitating the limitation of the second chest band 22 and the elastic band 23 in the horizontal direction and the vertical direction.

[0040] As shown in Figure 3 and Figure 6 , the outer surface of the rotating column 55 and the inner wall of the plug slot 52 are both surface friction treated, and the outer surface of the limiting plate 54 and the inner wall of the limiting slot 53 are both surface friction treated.

[0041] According to the above structure, the surface friction treatment increases the friction between the rotating column 55 and the plug slot 52, the surface friction treatment increases the friction between the limiting plate 54 and the limiting slot 53, thereby increasing the friction between the plug block 51 and the plug slot 52, reducing the situation that the plug block 51 and the plug slot 52 rotate to cause the second chest band 22 and the elastic band 23 to be separated, and improving the reliability of the device.

[0044] According to the above structure, the first chest band 21 and the elastic band 23 are detachably connected together through the first snaps 61 and the second snaps 62, which facilitates the disassembly and assembly of the elastic band 23 and the first chest band 21, thereby facilitating the disassembly and assembly of the elastic band 23.

[0045] As shown in the figure, Figure 8 The shoulder strap assembly 12 includes a connecting band 71 fixedly connected at both ends of the top of the first pad 10, respectively, and the end of the connecting band 71 away from the first pad 10 is pasted together with the second pad 11.

[0046] It should be noted that the end of the connecting band 71 away from the first pad 10 is fixedly connected with a fifth pasting part 72, and the second pad 11 is fixedly connected with a sixth pasting part 73, and the fifth pasting part 72 and the sixth pasting part 73 together constitute a magic tape, which is a prior art, for realizing the quick pasting and damage-free separation of the fifth pasting part 72 and the sixth pasting part 73, the sixth pasting part 73 is the hair surface of the magic tape, and the fifth pasting part 72 is the hook surface of the magic tape, which is used to reduce the exposure of the hook surface after the pasting of the fifth pasting part 72 and the sixth pasting part 73, causing discomfort to the patient, and the length of the sixth pasting part 73 is greater than that of the fifth pasting part 72, which is used to adjust the pasting position of the fifth pasting part 72 and the sixth pasting part 73.

[0047] According to the above structure, when it is necessary to adjust the length of the part of the connecting band 71 between the first pad 10 and the second pad 11, the fifth pasting part 72 and the sixth pasting part 73 are separated and then pasted together again, and by adjusting the overlapping position of the fifth pasting part 72 and the sixth pasting part 73 when they are pasted again, the length of the end of the connecting band 71 away from the first pad 10 overlapping with the second pad 11 is adjusted, thereby adjusting the length of the part of the connecting band 71 between the first pad 10 and the second pad 11, adapting to patients of different body types, and improving the applicability.

[0048] The working principle of the present application is that the looseness of the plurality of elastic bands 23 is adjusted by sliding the second chest band 22, when the patient inhales to expand the chest, the second pad 11 and the first pad 10 are away from each other, driving the plurality of elastic bands 23 to be converted into the stretched state in sequence, so that the limit of the chest expansion is gradually increased, reducing the situation that the initial limit of the chest is too large to expand the chest, reducing the discomfort of the patient, when the patient exhales to shrink the chest, the second pad 11 and the first pad 10 are close to each other, driving the plurality of elastic bands 23 to be converted into the relaxed state in sequence, until only one elastic band 23 at each end of the first pad 10 is in the stretched state, at this time, it is still in the normal limit state, reducing the situation that the initial limit of the chest is too small to be limited by the band after the chest shrinks, improving the reliability of the positioning, thereby improving the convenience of the trauma positioning.

[0049] The above is only the preferred embodiment of the present application, it should be pointed out that for the ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structure, device and operation method not specifically described and explained in the present application, such as no special description and limitation, are implemented according to the conventional means in the art.
